This invention aims to provide a simple means whereby ice may be shaved up for use in drug stores, soda bars, and elsewhere, when finally divided ice is needed. The invention aims to provide novel means whereby the ice will be fed by gravity against the member which cuts up or shaves the ice.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the inven' tion appertains.

With the above and other objects in view,

which willappear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodimentof the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in side elevation, a device constructed in accordance with the invention,

parts being broken away;

Figures 2 and 3 are sections, respectively, on the lines 22 and 33 of Figure 1;

Figure 4: is a plan of the cutting blade.

The numeral 1 marks the support or casing of approximately circular outline, made up of members 2 and 3 having marginal flanges 1 connected by bolts 5.

The casing 1 has an offset 6 in which is housed a pinion 7 on the shaft 8 j ournaled in the members 2 and 3 of the casing 1. The shaft 8 extends out through the member 3 of the casing and is connected to a prime mover 9 (of any desired sort, such as an electric motor) mounted on a shelf 10 connected to the member 3 of the casing and sustained thereon by brackets 11. The shelf 10 has an extension 12 secured at 14 to a standard 15. The member 3 of the casing 1 is provided with a projection 16 located opposite to the extension 12 and connected at 17 to a standard 18 which may be constructed like the standard 15.

The members 2 and 3 of the casin 1 have central hubs 19 in which is mounte a shaft 0 20 carrying a rotatable member 21 located 1928. Serial No. 288,887.

within the casing 1, and preferably in the form of a gear wheel, the teeth 22 of which mesh with the pinion 7. The rotatable memher or gear wheel 21 has radial openings 23 provided with inclined walls 2 1 on which blades 25 are adjustable at an acute angle to the side surface of the gear wheel 21. The blades 25 have transverse elongated slots 26 in which are mounted clamping devices 27, such as screws, mounted in the gear wheel 21. By loosening the screws 27, the blades 25 may be adjusted in and out, so as to regulate the amount that the blades bite into the ice during the shaving operation.

The member 3 of the casing 1 carries an in let chute 28. The wall 29 of the inlet chute 28 which is opposite to the gear 21 is inclined downwardly and inwardly, as shown in Figure 3, and when a chunk of ice is placed in the chute 28, the ice is held by gravity against the rotary member 21, owing to the slant of the wall 29. As shown at 30 in Figure 1, the chute 28 curves as it extends downwardly, to follow the general peripheral outline of the casing 1. The opening 31 in the member 3 of the casing, which communicates with the chute 28, is of the same area as the chute.

The member 2 of the casing 1 has a vertical outwardly projecting discharge chute 32, which is opened at both ends, as shown at 33. The discharge chute 32 is located opposite to the intake chute 28, as Figures 1 and 2 will show.

The inclined wall 29 of the inlet chute 28 holds the ice by gravity against the gear wheel 21, and when the gear wheel is rotated, the adjustable blades 25 shave the ice, the ice passing through the openings 23 in the gear wheel 21 and moving downwardly through the discharge chute 32. The gear wheel 21 is rotated from the motor 9 by way of the shaft 8 and the pinion 7.

The device is absolutely automatic, so far as feeding the ice is concerned. The ice 1 simply is cast into the inlet chute 28, and the wall 29 holds the ice against the side of the gear wheel. 21 in the path of the shaving blades 25,

The casing 1 has oppositely disposed re tion prevents leakage of water around the V Having thus described shaft 20, and conduces to a dry machine. The dryness of the machine is promoted, further, because the shaft 8 is located well above the center of rotation of the'member 21. Because the pinion 7 meshes with the gear teeth 22 at a point well above the center of rotation of the member 21, and because theice is delivered through the chute 28 at a point below the center of rotation of the member 21, the pinion and the gear, at their place of meshing, do not operate in water or in comminuted ice.

the invention, what is claimed is i i 1. A machine for comminuting ice, comrising a member supported for rotation and having an opening, means on said member for comminuting ice at the opening tocause the comminuted ice to passthrough the opening, and an inlet chute, the outer wall of which slopes to one side surface of said member, to

define therewith an angle so acute as to retain small pieces of ice against said surface and in the path of the comminuting means, the chute being curved in the direction of rotation of said member, to correspond with the path traversed by the comminut-ing means when said member is rotated, and the chute being extended to a point which is lower than the axis of rotation of said member.

2. A machine for comminuting ice comprising a casing, a rotary member j ournaled in the casing and having a peripheral gear, a pinion inside the casing and disposed at a higher elevation than the center ofrotation of said member, the pinion meshing with the gear, a prime mover supported on the casing and connected to the pinion, and ice-comminuting means on the rotary member.

3. A machine for comminuting ice comprising a casing, a rotary member journaled in the casing and having a peripheral gear, a

pinion inside the casing and disposed at a higher elevation than the center of rotation of said member, the pinion meshing with the gear, means on the rotary member for comminuting ice, mechanism for delivering ice to the ice-comminuting means at place lower than thecenter of vrotation of said member, and a prime mover supported on the casing and connected to the pinion.

4. A machine for comminuting ice, com

prising a casing having oppositely disposed recesses, a rotary member journaled in the casing and having a hub extended into the recesses and cooperating with the recesses at its ends, the hub having deflecting surfaces which extend out of the recesses,*the rotary memberibeing supplied with a peripheral gear, a pinion inside the casing and disposed at a higher elevation than the center of rotation of said member, the pinion meshing with the gear, ice-comminuting means on said member, and mechanism for delivering ice to the ice-comminuting means at a place lower than the center of rotation of the said member.

5. An ice shaver comprising a member supported for rotation, ice-shaving means on said member, an inlet chute and an outlet chute disposed on opposite sides of the said member, the outlet chute being open both at the top and at the bottom and presenting a ti rough unencumbered passage from the top of the chute to the bottom of the chute, whereby the chute may be freed of shaved ice which may have accumulated therein.

6. An ice shaver comprising a member supported for rotation, ice-shaving means on said member, an inlet chute and an outlet chute disposed on opposite sides of the said member, the outlet chute being open at both the top and the bottom and presenting a substantially vertical, straight, uninterrupted passage from the top of the chute to the bottom of the chute, whereby the chute may be freed of shaved ice which may have accumulated therein.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature KENNETH R. HARMON.
